SXSW is letting the people help decide which panel submissions are going to make it into the 2007 event. Lindsey Simon, for SXSW, put together this web page showing the submissions and allowing users to pick up to ten panels. Choosing a panel causes it to appear in the list of Picks, and the list items are draggable, so you can prioritize your picks.

The SXSW Panel Proposal Picker is built with Prototype and Scriptaculous.
